Application of the R-project package in the area of the multiple-comparison procedures
In our paper, we give the simulation
results concerning the multiple-comparison
procedures, especially their error measures,
such as FWER and FDR. We compare the
powers of four popular multiple-comparison
procedures, applied to three standard statistical
models. All of our simulations were carried
out by using the R-project package
Coastline evolution at different time scales - examples from the Pomeranian Bight, southern Baltic Sea
Sedimentological and morphological changes on the upper and lower shoreface during relatively stable sea-level highstand conditions have been investigated in the Pomeranian Bight, southern Baltic Sea, at time scales ranging from storm events to millennia. In order to cover that variety of time scales, different methods have been applied. Seasonal variations in the morphology of the upper shoreface were measured accurately using the tracer stick method. The ratio of breaking waves and energy dissipation due to wave breaking are the main forces controlling redeposition on the upper shoreface with the depth of disturbance up to three times the net change. The impact of single storm events can be observed from sidescan sonar mosaics to remain on the decadal scale. Aerial photographs covering the upper shoreface show that the location of gates, channel-like systems where water masses move offshore created during storm events, also remain stable over decades. Sedimentological and geomorphological variations and changes on the lower shoreface are only measurable on the century to millennium scale because the main driving forces are longlasting processes like sea-level fluctuations or neotectonics. Data on these scales have much more uncertainty in their relationship to forcing functions than data at shorter time scales. Because the effects of coastal processes active on different time scales can interact, comprehensive understanding of large-scale coastal behavior requires investigations from short events to long-term processes.

Analysis of climatic and hydrologic parameters variability in the Biebrza River basin
Wetlands are endangered ecosystems.
The main, most observe and forecast risk for
the wetlands is global climate change. The
paper presents the analysis of multiyear tendencies
of changes of climatic and hydrologic
characteristics in the Biebrza River basin
in 1966–2003 with the use of Mann-Kendall
test. The analysis of climatic characteristics
let to state, that climate warming is noticeable
in Poland and in the Biebrza River too.
In case of the analysis of hydrologic characteristics
the changes are less noticeable. Nevertheless
we can talk about the initial phase
of lowering of maximum water levels and of
maximum discharges which in decisive way
infl uence the wetlands
New cladosporium species from normal and galled flowers of lamiaceae
A series of isolates of Cladosporium spp. were recovered in the course of a cooperative study on galls formed by midges of the genus Asphondylia (Diptera, Cecidomyidae) on several species of Lamiaceae. The finding of these fungi in both normal and galled flowers was taken as an indication that they do not have a definite relationship with the midges. Moreover, identification based on DNA sequencing showed that these isolates are taxonomically heterogeneous and belong to several species which are classified in two different species complexes. Two new species, Cladosporium polonicum and Cladosporium neapolitanum, were characterized within the Cladosporium cladosporioides species complex based on strains from Poland and Italy, respectively. Evidence concerning the possible existence of additional taxa within the collective species C. cladosporioides and C. pseudocladosporioides is discussed
Short-term whole body vibration exercise in adult healthy horses
The purpose of this study was to analyze the acute effect of whole body vibration exercise (WBVE) on clinical parameters and blood values in horses. Seven horses were exposed to a 10 min WBVE at a frequency of 15-21 Hz. Clinical parameters and venous blood samples were taken before and directly after WBVE. Acute short-term WBVE produced a decrease in serum cortisol (p=0.02) and creatine-kinase (p=0.02) values. Clinical parameters, hematology, fibrinogen, lactate, IGF-I, GGT, creatinine, myeloperoxidase activity and bone marker values were not significantly changed by WBVE. In adult sound horses WBVE was well tolerated and did not cause any sign of measured discomfort
